TYPOGRAPHICAL Specification. of Letters intent.

PatentediSept. 14, 1915.

. v graphical 'Machines, of which the following is a specification,reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotypemachines of the general organization represented in Letters Patent ofthe United States No. 436,532, to O. lliergenthaler, wherein circulatingmatrices are released from a magazine in the order in which theircharacters .are .to appear in print and .then assembled in line, the

composed line transferred to the face of a ,mold, the mold filled withmolten metal to form a slug or linotype against the matrices whichproduce the type characters thereon, and the matrices thereafterreturned through distributing mechanism to the magazine from which theystarted. 7

More particularly, it relates to means comprising an automatic signal toindicate to the operator the presence of an'improper matrix in acirculating group thereof. In the present instance these means areillustrated in connection with the devices for delivering the matricesto the ,distributer, but they may alsobe employed for the same purposein other locations, if it be desired.

In the accompanying drawings, I have shown my invention only inpreferred forms and by way of example, and .as applied to a linotypemachine. However, many changes and variations :may be made therein, andin its mode of application, which will still be comprised within itsspirit. Similarly, it may be applied to other forms of typographicalmachines, such as typesetters, typecasters and the like, which handletype or dies, instead of matrices. Generally speaking, I desire it to beunderstood that I do not limit myself to any specific form orembodiment, except in so far as such limitations are specified in theclaims.

Referring to the drawings: Figure 1 is a front elevation, partly brokenaway, of the distributor box, etc, of a linotype machine, with myimprovements embodied therein; Fig. 2 is a somewhat similar view showingsome of the parts in different position; Fig. 3 is a section on the line3-3 of Fig. 1;

Fig. is a detail; and Figs. 5, 6, 7, and 8 are views illustratingvarious modifications.

Referring first to Figs. 1, 2, '3 and 4, the matrlces X are individuallyelevated and del vered by the lifting .device A to the screws 13 anddistributer C, whereby they are restored to the proper channels in themagazine. Moreover, the matrices are each formed in their loweredgeswith notches X the location of which varies according to font, all inthe manner understood in the art. These parts may be of any desired orapproved construction, and in themselves constitute no part of mypresent invention.

Located in advance of the lifting device A lsthe font distinguisher orfinger D, which normally projects upwardy into the path of the matricesand in registration with the notches 'X of the particular font in use,so that the matrices of this font are allowed to pass unimpeded to thelifting device. The d istinguisher or finger D is mounted upon the shortrotatable shaft E, which is provided at its end with the button F andthe grooves G, intended to be engaged by the pivoted latch (Figs. .3 and4), this construction permitting the longitudinal adjustment of theshaft and the location of the finger in different positions according tofont; The shaft E is located within the sleeve J, which is rotatablymounted in the frame, and is formed with a longitudinal slot throughwhich the finger D projects, so as to insure the rotation of the sleevewith the shaft but still permit the longitudinal adjustment of thelatter. (1onnected .to the sleeve is the projecting arm or striker Klocated in suitable position to ring the bell L mounted upon the frame.

The operation of the parts will be readily understood. When matrices ofproper font are being delivered notches X finger D in D (Figs. 1 and 3),their register with and pass over the the usual manner, leaving it andthe connected parts at rest. However, if an improper matrix, such forinstance as one with a differently located notch, or one without anotch, or a reversed matrix, be presented to the finger (Fig. 2), thelatter will be swung laterally together with the shaft E and sleeve J,and the striker K will be raised to active position. When this matrix isremoved, as by the action of the lifting device A, the parts are free toresume their normal condition, and the striker rings the bell. In thisWay the operator is notified of the presence of an ofi'ending matrix,and he may proceed to correct the difficulty. 7

Instead of an audible signal as above described, a visual one may beemployed, as illustrated in Fig. 5. In this instance the signal takesthe form of a disk M suspended bv the vertical shaft N and held normallyby the spring 0 in an inconspicuous position, such as edgewise to thefront of the machine. Mounted upon the sleeve J is the depending arm Pengaging the end of an arm Q, upon the shaft N, so that when an impropermatrix contacts with the distin- J guishing finger, the shaft N isrotated and the disk'swung to present its face to the operator, as shownby dotted lines, and thus indicate the presence of a Wrong matrix.

Fig. 6 illustrates a different form of audible signal, comprising theratchet wheel It, the tensioned spring R connected thereto, and thestriker R arranged to ring the bell B In this instance a pawl S isconnected to the sleeve J andengages the ratchet It, so that when thedistinguisher is moved, the pawl V is freed from the ratchet, and thealarm is sounded.

In Fig. 7 are illustrated electrical devices, comprising the normallybroken circuit U connected with a battery or other source of energy Uand an electric bell V. In this instance an arm T upon the sleeve J actsto close the circuit and ring the bell when the distinguisher is moved.Fig. 8 presents similar electrical devices connected to a visual signal,comprising the circuit Y, source of energy Y and concealed disk Z, whichis moved into the view of the operator when the arm W on the sleeve Jcloses the circuit. 1

As previously stated, I have shown my invention only by way of exampleand in one or more preferred forms. Obviously, however, manymodifications and alterations therein, and in its mode of adaptation,will suggest themselves to those skilled in the art, without departurefrom its scope.

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States, is as follows:

1. In a typographical machine, the combination of distributingmechanism, a group Copies of this patent may be obtained for five centseach, by addressing-the of type or matrices movable through the machinefor delivery thereto, and an automatic signal distinct from thedistributing mechanism and adapted to be operated by an improper type ormatrix in'the group.

2. In a typographical machine, the combination of distributingmechanism, a font distinguisher to control the delivery of type ormatrices thereto, and an automatic signal distinct from the distributingmechanism and controlled by the font distinguisher.

3. In a typographical machine, the combination of distributingmechanism, a fontdis tinguisher adjustable to difierent operativepositions to control thedelivery to the distributing mechanism of typeor matrices of different forms or fonts, and an automatic signaldistinct from the distributing mechanism and controlled by the fontdistinenter the notches therein; whereby the presence of an improperlynotched matrix in the group'will engage said device and cause it tooperate the signal.

5. In a typographical machine comprising type or matrices of diiferentforms, the.

combination of distributing mechanism, means for moving the type ormatrlces through the machine for delivery to the distributing mechanism,an automatic signal distinct from the distributing mechanism, and anactuating device therefor arranged in the path of movementof thetype crmatrices and adapted to permit the passage of type or matrices of oneform and adapted to be engaged by the passing type or matrices ofanother form so as to operate the signal. e

In testimony whereof, I have afiixed my signature in presence of twowitnesses.
